Elevator and lift components
Elevator parts are geometry-critical and coated for a shaft environment that is often damp. Ganesh makes counterweight frames, car frames and slings, guide rail brackets, rail clips and fishplates, cabin and door panels, floor sills and controller enclosures for TKE and Eros Elevators. These guides cover each part family: material, forming and welding route, the tolerances that matter at installation, coating specification, inspection and what a lift OEM should put on the drawing.
